Apple tree named ‘Fuji VW’

ABSTRACT

‘Fuji VW’ apple is a ‘Fuji’ sport notable for its fruit, which is fully colored well before harvest, and has a distinctive solid red-purple overcolor. ‘Fuji VW’ can be harvested in a single picking.

Latin name: Malus domestica Borkh.

Variety denomination: ‘Fuji VW’.

BACKGROUND OF THE VARIETY

‘Fuji VW’ is a new and distinct variety of apple tree (Malus domestica Borkh), which originated as a limb sport mutation of ‘Brak’ Fuji (U.S. Plant Pat. No. 15,261). ‘Fuji VW’ was discovered by the inventor in a cultivated orchard at Girlan, Eppan, Italy in 2009, and was selected for further observation for its vigorous spur production and distinctive early and even coloring of fruit. ‘Fuji VW’ was first asexually propagated by chip budding in 2010 at Presina, Italy, and has since been observed to remain true to type over successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘Fuji VW’ was first selected for its spur vigor and for its fruit, which is fully colored well before harvest. A comparison of ‘Fuji VW’ to parent ‘Brak’ Fuji and to similar varieties ‘Aztec’ Fuji (not patented) and ‘Fuji Fubrax’ (U.S. Plant Pat. No. 18,761) is set forth below.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following detailed botanical description of ‘Fuji VW’ apple tree is based on observations made during the 2014 and 2015 growing seasons at Cornaiano, Italy of trees planted in 2012 on M9 T337 virus free rootstock. All colors are described according to The Royal Horticultural Society Colour Chart (2001). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant or any group of plants of the new variety may vary from the stated average.
